摘要： Embodiments of the present disclosure include a screen basket apparatus includes a substantially vertical cylindrical frame and a synthetic screening surface secured to the frame. The synthetic screening surface may be configured to separate carbon or resin from a slurry of a carbon-in-leach, carbon-in-pulp, resin-in-leach, or resin-in-pulp material as fluid flows from outside to inside the screen basket apparatus such that carbon or resin is retained on an external surface of the synthetic screening surface. The cylindrical frame may be a grid frame and the synthetic screening surface may include a plurality of replaceable screen assemblies attached to the grid frame. The grid frame may include a plurality of openings and each of the plurality of openings is configured to receive a respective one of the plurality of replaceable screen assemblies. The synthetic screening surface may include injected molded thermoplastics, thermoset polyurethanes, and/or other polymeric materials.

摘要： A method for producing a cylindrical screen device with a plurality of profiled bars. The outer face of a plurality of mutually spaced annular bar holders, which are arranged perpendicular to the cylinder axis, are provided with recesses that are open at the edges. The recesses have a shape that substantially corresponds to the base of profiled bars in a complimentary manner. The recesses are marginally larger than the bases. The profiled bars are inserted into respective recesses, parallel to one another and parallel to cylinder axis.

摘要： A bar-type screen cage has profiled screen bars which are spaced apart in a circumferential direction. Multiple support arrangements which are spaced apart in an axial direction of the screen cage are fastened by welding to the profile bars at the outside. The screen bars, which are spaced apart in an axial direction, form screen slots between them. Each support arrangement includes at least two support wires which are closely spaced apart in the axial direction of the screen bars and which are fixed to the screen bars by resistance welding. The two support wires of each support arrangement and the profile bars-are fixedly connected to one another by way of an additional weld seam.
